1.配置插件

<plugin>
                    <groupId>com.spotify</groupId>
                    <artifactId>docker-maven-plugin</artifactId>
                    <version>0.4.13</version>
                    <configuration>
                        <imageName>${docker.image.prefix}/${project.artifactId}</imageName>
                        <baseImage>java:1.8</baseImage>
                        <entryPoint>
                            ["java","-Djava.security.egd=file:/dev/./urandom","-Dspring.profiles.active=test","-jar","/eshop-server.jar"]
                        </entryPoint>
                        <imageTags>
                            <imageTag>${project.version}</imageTag>
                        </imageTags>
                        <dockerDirectory>src/main/docker</dockerDirectory>
                        <resources>
                            <resource>
                                <targetPath>/</targetPath>
                                <directory>${project.build.directory}</directory>
                                <include>${project.build.finalName}.jar</include>
                            </resource>
                        </resources>
                    </configuration>
                </plugin>

imageName: itmuch/microservice-discovery-eureka:0.0.1   用于指定镜像名称，其中itmuch是仓库名称，microservice-discovery-eureka是镜像名称，0.0.1是标签名称

baseImage:用于指定基础镜像，类似于Dockerfile中的FROM指令

entrypoint：类似于Dockerfile的ENTRYPOINT指令

resources.resource.directory:用于指定需要复制的根目录，$\{project.build.directory\} 表示target目录

resources.resource。include:用于指定需要复制的文件。$\{project.build.finalName\}.jar 指的是打包后的jar包文件

2.执行命令，构建Docker镜像

mvn  clean  package  docker:build

3. 查看刚刚构建的镜像  docker images

4.启动镜像

docker  run  -d -p  8761:8761  itmuch/microservice-discover-eureka:0.0.1
